Congestion Avoidance in 0.6

[Tommi Laukkanen]

Hi

To be compliant with TCP congestion avoidance strategy we could also
implement something according to the lines of TCP specification.
Currently we do not get duplicate ACKs for not guaranteed packets but
we could change it so that we acknowledge all packets to allow sender
to count all packet drops and do throttling accordingly:
